Purpose: Describe the hardware specifications and architectural design of Fitolo devices for retrofitting on gym equipment.
- Fitolo offers a range of smart devices that can be retrofitted on gym equipment.
- Each device includes:
- A User Board: handles interaction via ID device, push button, and indicator.
- A Sensor Board: collects exercise-specific data.
- The User Board connects to a Gateway, which links to a Cloud backend.
- A prototype mobile app is available for users to interact with cloud data.
| Parameter | Sensor Board | User Board | Gateway |
